What is a rear flip kit and C-notch?

A rear flip kit repositions your truck's rear axle to sit above the leaf springs, achieving a significant drop. A C-notch is a frame reinforcement that creates clearance for the axle as it moves up and down, preventing interference and maintaining structural integrity after the frame has been cut.

What tools are needed for this installation?

This kit requires cutting and welding for the C-notch installation. You will also need standard suspension tools, jack stands, and a floor jack. Refer to the manufacturer's instructions for a complete tool list and procedure.

Does this kit include everything for the rear drop?

Yes, this kit includes the rear flip kit, rear C-notch frame support, rear shock angle corrector, and front and rear Maxtrac shocks, providing a complete package for a 6-inch rear drop.

Product Details

If you're looking to give your 1999-2006 GMC Sierra 1500 a significantly lower stance, this 6-inch rear lowering kit from Maxtrac is designed to get the job done. This kit focuses on bringing the rear axle up and over the leaf springs, a common method for achieving a substantial drop on trucks from this era. It's a popular choice for those aiming for a custom look and improved handling characteristics that come with a lower center of gravity.

Inside this kit, you'll find everything needed to perform a 6-inch rear drop. It includes a rear flip kit, which is the core component that allows the axle to sit above the leaf springs. To ensure structural integrity after the modification, a rear C-notch frame support is included, reinforcing the frame where the axle might otherwise interfere during suspension travel. You also get front and rear Maxtrac shocks, specifically chosen to work with the lowered suspension geometry, and a rear shock angle corrector to maintain proper shock absorber function. Keep in mind that performing this type of modification requires cutting into the frame for the C-notch installation, so be prepared with the right tools and a solid plan.

This kit is a comprehensive solution for lowering the rear of your 2WD V6 or V8 Sierra 1500. By addressing the axle placement, frame clearance, and shock angles, Maxtrac aims to provide a complete package for a successful installation. Ensure you have the necessary tools and knowledge for frame cutting and welding, as these steps are critical for safety and proper function.
